To all whom it may concern:

Be it known that I, RICHARD LORENZ, asubject of the King of Prussia, German Emperor, residing at Rummelsburg, near Berlin, Prussia, Germany, have invented a new and useful Improved Wire-Drawing Machine, of which. the following is a description.

The present invention relates to machine's for simultaneously drawing several wires; and it consists of the details of construction as hereinafter set forth.

In order to render the present invention easily intelligible, reference is had to the accompanying drawings, in which Figuf'e 1 is a front view of the machine. Figs. 2 and 3 are side views of the supports for the diamond-holders. Fig. 4 is a top view of the support, and Fig. 5 a diagram of the uiding of the wires.

T e wire I is guided around the guidingroller 2, loosely mounted on-the shaft 1, and passes through the drawing-iron 3, Figs. 2, 3, and 4, from here two'times around the drawing-roller 5, secured faston the shaft 4, and then to the next higher guiding-roller 6 of the larger set of guiding-rollers A. After the wire I has successively passed all the drawing-irons of the rear drawing-mill Band been guided around all the guiding and drawin rollers of the set of rollers A and C, respectively, it goes at 20 to a drum, similar to the drum 7 of the next drawing-mill. The

" wire I, coming from the uppermost guidingroller of the preceding drawing-mill, similar to that herein described, is correspondingly wound on the drum,7, which is fasten the shaft 1. The wire I I is at first guided around the smallest loose roller 8 of theset of guiding-rollers D, passes from there through the lowermost drawing-irons of the front row E, then to the lowermost roller 9 of the drawingmill F, and finally, after having passed the several drawing-irons of the front row E, ar-

rives at the drum 10, which is fast on the shaft 4.

The drawing-irons are rotated as usual and driven in the following manner, Figs. 2, 8, and 4: The spindle 1 1, which is driven by a pulley arranged below the working table, carriesat its head a worm 12, which engages with a worm-wheel 13. The shaft of the worm-wheel 13, which is mounted in the bearing 14, carries at the other end of the.

bearing a spur-wheel 15, which in turn engages'with the spur-Wheel 16 of the uppermost drawing-iron holder of the front row E.

The uppermost spur-wheel 16 engages in turn the spur-wheel of the-next following drawingiron holder, and this spur-wheelengages the next following spur-wheel, and so on, so that thusdthe entire front drawing-iron row E is rotate The reardrawing-iron row B is rotated in the following manner: At the rear side of all the front wheels of. the front drawing-iron row E conical wheels are arranged, which are in engagement with conical wheels at the drawing-iron row of the rear row Bf For example, the conical wheel 17 at the uppermost spur-wheel 16 is in engagement with the conical wheel 18 of the uppermost drawing-iron holder 19 of the rear part of the row B. The second uppermost wheel of the front row E drives in turn the second uppermost wheel of the rear row B by means of conical wheels, and so on. Instead of the conical wheels spurwhee1s may be employed.

The'distanceapart of two adjacent-rollers ofthe same roller setfor instance, of the rollers 2 and 6over which the same wire I passes is governed b the size of the drawingiron holder. This istance apart cannot be diminished, since the size of the drawingiron holders cannot be reduced. In this invention, however, parallelly to the first row of drawing-iron holders for the wire I a second row of drawing-iron holders is arranged, through which the wire I I passes, which,,as herein described, is guided over special guiding and drawing rollers lying between those of the first wire. Thus the room which has hitherto been used for the production of a single production.

ameter than and alternating with the corresponding guiding-rollers of the other set, two sets of conical drawing-rollers, those of one set being larger thanand alternating with the corresponding rollers of the other set, all of the guiding-rollers being on one axis and all of the-drawing-rollers on another axis and two sets of drawing-irons arranged between the guiding-and drawing rollers, said sets of drawing-irons being intwo parallel rows and in the same plane, substantially as described.

2. In combination two sets of conical guiding-r0llers, those of one set being larger in diameter than and alternating with the corresponding guiding-rollers of the other set, two sets of conical drawing-rollers, those of one 2 ai time set being larger than and alternating with the corresponding rollers of the other set, all of the guiding-rollers being on one axis and all of the drawing-rollers on another axis, two sets of drawing-irons arranged between the guiding and drawing rollers, said sets being in two parallel rows and in the same plane and means for rotating said drawing-ironconsisting of intermeshing gears on one row I and-intermeshing gears between the opposing ro irons of the two rows;

In testimony whereof I afiix my signature in "thepresenoe of twowitnesses.
